Abstract
To provide a package bag that can be easily opened, while preventing unintentional breakage or opening. A flexible film package bag 1 comprises: a sealed portion 2 in which a flexible film is joined; and a plurality of notches 4 for opening. The plurality of notches 4 are provided in such a way that an end thereof on an outer edge portion 6 side of the flexible film package bag 1 is positioned away from the outer edge portion 6 by a predetermined distance. Since the outer edge portion 6 has neither a cutout nor slit and all notches 4 are away from the outer edge portion 6, there is no risk of unintentional breakage or opening and the package bag can be easily opened as necessary.
